To @ZZ whom it may concern:

Be it known that I, WILLIAM A. LANCK- TON, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Flush-Valves, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to improvements in flushing-valves for controlling the discharge of flushing-tanks; and its object is to provide means, controlled by the outgoing water, for automatically holding the valve, as long as the iiow of water continues, in any position to which it may be raised by the operator.

A further object oi the invention is to so construct and arrange the valve and parts that the same may be readily detached and removed from their bushing for the purpose oi cleaning or repair and to provide the device with certain other new and useful features, all as hereinafter more fully described, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of a device embodying the invention and showing the .valve held in its raised position; Fig. 2, a horizontal section of the saine on the line a; x of Fig. 1, and Fig. 3 is a perspective view of the va ve and its supporting-bracket and gripper detached Jfrom the bushing.

As shown in the drawings, 1 is a suitable bushing i'itting an opening in the bottom 2 of the Hush-tank and secured therein by externally screw-threading the lower end of the bushing to receive a ring-nut 3, adapted to engage the outer side of the tank-bottom, a flange 4 being provided on the bushing, with a gasket 5 interposed between it and the inner side of the tank-bottom to make a tight joint. The upper end of the bushing is formed with an inclined valve-seat 6, and an overflow-pipe 7 opens into the bushing below said seat. An inwardly-extending continuous annular rib 8 is formed integral with the bushing intermediate its ends, and a corresponding interrrupted rib 9 is provided above the rib 8 and at a short distance therefrom.

A detachable bracket 10 is formed with arms extending diainetrically across the bushing and having segmental ends 11, adapted to be engaged between the ribs 8 '24, through which said stem projects.

tached to the lower side oi the valve 14,60 which valve is adapted to engage the seat 6 on the upper end of the bushing. The bearing 12 on the bracket is provided with a vertical slot 15 for a pin 16 on the valve-stem which pin prevents the rotation of the stem and Jforms a stop by engaging the upper end of its slot to prevent the valve from being lifted too far. Extending upward from the upper side of the valve is a rod 17, bent latera ly at its upper end, and a liftin -rod 18 is. provided with a loop at one en through which the rod 17 extends, and is attached at its opposite end to any suitable lever (not shown) for raisinO the rod to engage its loop with the bent end of the rod 17 and lift the valve, said valve being thus free to rise or fall independently of the lifting-rod.

To hold the valve in the position to which it may be raised by the lifting-rod until the water contained in the tank has escaped, an automatic gripping or clutch device 19, formed of sheet metal, is provided, consisting of a vertically-extending gravity-arm 20, which is bent at right angles near one end, and this bent end 21 is formed with an opening 22 of slightly larger diameter than the diameter of the valve-stem 13, which extends therethrough, the said end 21 resting upon the upper end oi the bearing 12, with the arm' normally hanging vertically downward at one side of said bearing. The lower end of the arm 20 is broadened into an oval' or spoon-shaped end 23, forming a delector which is bent laterally toward the valvestem and provided with a longitudinal slot The gripping device being supported by the engagernent of the end 21 with the upper end v of the bearing 12 is free to swing, and the de- Hector 23 being bent laterally extends across the vertical path oi the water as it passes through the bushing, so that when the valve is opened the falling 'water will engage the deilector-and swing the gripping device, causing the edges of the opening 22 therein to engage the sides oi the valve-stem which passes through said opening and grip the saine, so that the valve cannot seat until the IOO water in the tank has passed off, and having ceased to fall upon the deflector permits the gripper to swing backto the vertical, thus releasing the stem.

A ilange 25 is provided on the upper end of the bearing l2, and a projection 26 on the arm of the gripper engages beneath flange to prevent the gripper from being raised by the valve-stem.

The valve and parts contained within the bushing may be quickly and easily removed by turning the bracket until the segmental ends on the supporting-arms are disengaged from the interrupted flange, or are opposite the cnt-away portions thereof, and then lifting the bracket out. A new rubber edge or packing 27 may then be easily sipped into the' groove provided therefor in the periphery of the valve, or any other needed repairs made, and the parts again secured in p ace by passing the said segmental ends downward between the parts of the interrupted ilange into engagement with the lower ilange and then turning the bracket until the ends lie between the flanges and come in contact with the stop 28 at one end of each part of .the interrupted lange.

It is evident that the gripper will operate to hold the valve in any position to which it is lifted,- for as soon as the valve is raised the water will begin to pass through the bushing and striking the deiiector will swing the arm and cause the valve-stem to bind in the opening therein. The lifting-rod 18 is connected to the rod on the valve vby means of its loop, so that there will be a lost motion Ibetween the rodsthat is, so that the loop may operate to lift the valve and then slide down on the valve-rod, the valve being held in its raised position by the gripper, and thus the valve is left free to fall by its own weight when released by the gripper.

Having thus fully described my invention, what I claim isl. In a flushing-valve, the combination with a bushing having a valve-seat and a valve to engage said seat, of a guide-bearing in the bushing, a downwardly extending stem on the valve engaging said bearing, a gripper engaging the stem, and a deilector extending across the path of the water bclow the valve to operate the gripper.

2. In a flushing-valve, the combination' with a bushing having a valve-seat and an axial guide-bearing below said seat, and a valve to engage the seat, of a stem on the valve to engage the guide-bearing, a member provided with an opening of slightly-larger diameter than the diameter of the stem to receive said stem, and a de'Hector connected to said-member and adapted to be moved by the flow of the water released by the valve to tilt said member on said stem and bind the same in its opening.

with a bushing having a valve-seat and a valve to engage said seat, of a vertical guidebearing in the axis of the bushing, a valvestem on the valve movable in said bearing and a gripper consisting of an end portion provided with an opening to receive the stem wa n d of larger diameter than the stem supported by the upper end of the bearing, an arm rigidly secured to said end portion and adapted to normally hang downward at one side of the bearing, and an enlarged lower end on the arm extending across the vertical path of the water admitted to the bushing of the valve.

4. In a valve, the combination with a member formed with a valve-seat and a valve to engage said seat, of a stem on the valve, inwardly-extending parallel ribs on said member and a bracket formed with a guide-bearing for the stem and provided with arms the ends of which are adapted to be engaged between said ribs to detachably support the bracket.

5. In a valve, the combination with a tubular member formed with a valve-seat and a valve `to engage said seat, of a stem on the valve extending in the axis of the member, an inwardly-extending continuous rib extending circumferentially from the inner face of the said tubular member below the valve-seat, an yinterrupted rib parallel with and at a short distance from the continuous rib, a bracket formed with a guide-bearing for the stem and having laterally-extending arms, and segmental ends on said arms adapted to be engaged between the ribs to detachably support the bracket.

6. In a flushing-valve, the combination its upper end and a valve having a i'lexible packing-ring at its edge to engage said seat, or' a downwardly-extending axial valve-stem on said valve, a circumferential rib extending inward from. the bushing, an interrupted rib parallel to said rib, a bracket having laterally-extending arms, segmental ends on said arms to engage between the ribs on the bushing, stops on the bushing to engage said segmental ends, a guide bearing on the bracket for the stem formed with a longitudinal slot and a pin on the stem to engage said slot.

7. In a ilushing-valve, the combination with a bushing formed with a valve-seat at its upper end and a valve to engage said seat, of an axial valve-stem on the valve, a bracket detachably secured within the bushingl and provided with a vertical guide-bearing for the valve-stem and -having a vertical slot and a flange at its uppei1 end, a pin on the stem engaging the slot, and a gripper formed of sheet metal and consisting of an end portion bent at right angles and formed with an opening of larger diameter than the stem to receive In a iiushing-valve, the combination the same and engaging the upper end of the with a bushing formed with a valve-seat at lIO In testimony whereof I afEX my signature in presence of two witnesses.
